Participants > vote delegation: New permissions for principals (limit actions)

[MSoeb]

Description: At the current state, principals have the same permissions as proxys. For example, they can add themselves to the list of speakers or they can create motions/amendments. This permission system needs an improvement to restrict some permissions of principals (that are not present).

What should happen:
Add four new settings to limit the actions of principals which are not present.

• Principals may not place themselves on the list of speakers
• Principals may not submit motions/amendments
• Principals may not support motions

[MSoeb]

Need to discuss where this feature should be implemented. Add restrictions via vote delegation seems not to be a good option. We need to discuss options.

This will need significant backend changes, including meta changes -> backend issue is OpenSlides/openslides-backend#2348

The client should pay attention to correctly disable buttons in relation to the new backend-side restrictions
